Philip K. Dick (December 16, 1928 - March 2, 1982) was one of the finest American writers of the 20th century. His roots are in the pulp science fiction of the 1950s, but his best works (especially those of the '60s and '70s) burn with a purity of vision completely lacking in almost all other authors, whether "genre" or "literary."
